Abstract:Through an in-depth investigation was made in Lashanhe cave, a total of 472 animal specimens from Lashanhe cave which were belonged to 3 phyla, 9 claaes, 19 orders, and 38 species. Four communities were classified based on individual numbers and environmental differences. The analysis of community diversity showed that the diversity index of each community were: 2.6379(A), 2.4757(B), 1.4423(C), 1.3115(D), community A showed the highest species number and richness indices. Community D showed the highest evenness indices. Community C showed the highest dominance indices, although the species number of community C is lowest, it formed a larger group. By the pearson correlation coefficient, analysis indicates: the temperature was positively correlated with diversity of community (1.000). Aercury in soil was positively correlated with S (0.997), mercury in soil was correlated with H’ (-1.000), D (-0.999), C (0.998). Through the evaluation of soil pollution, seriously pollution of mercury and arsenic in Lashanhe cave, but the evaluation of water pollution showed that mercury and arsenic in Lashanhe cavea is reached the class iii quality standard for ground water. There is a close relationship between content of heavy metals and animal community structure.
